[MW:3396] Out of roundness for piping

Dear All

Regarding above mentioned subject, i would like to know the permissible limit of out of roundness for piping(straight pipe) because one of  our new spool found dented during fabrication. For vessel it clearly stated on ASME VIII div. 1 UG-80 but for piping B31.3 not. Only clause 332.2.1 bend flattening i found and guess related. Can i use 332.2.1 or UG-80 as a acceptance criteria. Please help me my friends. Your kind help is highly appreciated

Regards

Tong2je
